GCC Patch Revived For -mtune=generic Showing Nice Benefits On Intel & AMD CPUs

A 2021 era patch for the GNU Compiler Collection (GCC) has been revived and discussed in recent days around simplifying the memcpy and memset inlining strategies when compiling code with the “-mtune=generic” option. The patch takes the approach during that generic tuning to try to avoid branches. In doing so, some nice performance benefits are observed in some benchmarks…

Space Investor Sees Opportunities in Defense-Related Startups and AI-Driven Systems

Chad Anderson is the founder/managing partner of the early-stage VC Space Capital (and an investor in SpaceX, along with dozens of other space companies). Space Capital produces quarterly reports on the space economy, and he says today, unlike 2021, “the froth is gone. But so is the hype. What’s left is a more grounded — and investable — space economy.”

On Yahoo Finance he shares several of the report’s insights — including the emergence of “investable opportunities across defense-oriented startups in space domain awareness, AI-driven command systems, and hardened infrastructure.”

The same geopolitical instability that’s undermining public markets is driving national urgency around space resilience. China’s simulated space “dogfights” prompted the US Department of Defense to double down on orbital supremacy, with the proposed “Golden Dome” missile shield potentially unleashing a new wave of federal spending…

Defense tech is on fire, but commercial location-based services and logistics are freezing over. Companies like Shield AI and Saronic raised monster rounds, while others are relying on bridge financings to stay afloat…

Q1 also saw a breakout quarter for geospatial artificial intelligence (GeoAI). Software developer Niantic launched a spatial computing platform. SkyWatch partnered with GIS software supplier Esri. Planet Labs collaborated with Anthropic. And Xona Space Systems inked a deal with Trimble to boost precision GPS. This is the next leg of the space economy, where massive volumes of satellite data is finally made useful through machine learning, semantic indexing, and real-time analytics.

Distribution-layer companies are doing more with less. They remain underfunded relative to infrastructure and applications but are quietly powering the most critical systems, such as resilient communications, battlefield networks, and edge-based geospatial analysis. Don’t let the low round count fool you; innovation here is quietly outpacing capital.

The article includes several predictions, insights, and possible trends (going beyond the fact that defense spending “will carry the sector…”)

“AI’s integration into space (across geospatial intelligence, satellite communications, and sensor fusion) is not a novelty. It’s a competitive necessity.”
“Focusing solely on rockets and orbital assets misses where much of the innovation and disruption is occurring: the software-defined layers that sit atop the physical backbone…”

“For years, SpaceX faced little serious competition, but that’s starting to change.” [He cites Blue Origin’s progress toward approval for launching U.S. military satellites, and how Rocket Lab and Stoke Space “have also joined the competition for lucrative government launch contracts.” Even Relativity Space may make a comeback, with former GOogle CEO Eric Schmidt acquiring a controlling stake.]

“An infrastructure reset is coming. The imminent ramp-up of SpaceX’s Starship could collapse the cost structure for the infrastructure layer. When that happens, legacy providers with fixed-cost-heavy business models will be at risk. Conversely, capital-light innovators in station design, logistics, and in-orbit servicing could suddenly be massively undervalued.”

Pope Francis Has Died

Pope Francis has died at the age of 88, the Vatican said Monday. The pontiff, who was Bishop of Rome and head of the Catholic Church, became pope in 2013 after his predecessor Benedict XVI resigned. On February 14, the Pope was admitted to hospital for bronchitis treatment. From a report: Born in 1936, Francis was the first pope from South America. His papacy was marked by his championing of those escaping war and hunger, as well as those in poverty, earning him the moniker the “People’s Pope.” In 2016, he washed the feet of refugees from different religions at an asylum centre outside Rome in a “gesture of humility and service.”

He also made his views known on a wide range of issues, from climate change to wealth inequality and the role of women in the Catholic Church.

Return-to-Office Policies Are Impacting Neurodivergent Workers

With more companies requiring workers to return to an office five days a week, “Anxiety is rising for some of the millions of people who identify as neurodivergent,” writes the Washington Post.

They raise the possibility that “strict office mandates have the potential to deter neurodivergent people who may approach problems differently,” the article notes — affecting peoiple “whose brains function differently, such as with ADHD, autism or dyslexia.”

While many neurodivergent people excel in an office, others struggle with sensory issues, an inability to focus and exhaustion, workers say… About a fifth of U.S. adults self-identify as neurodivergent, with a majority saying they always or usually feel that their brain works differently, according to a recent survey by research and analytics firm YouGov. They cite issues such as starting tasks before finishing others, being overwhelmed by social situations and struggling to focus…

Some neurodivergent workers discovered success working remotely during the pandemic and don’t feel comfortable disclosing their diagnoses due to fear of and prior instances of discrimination. Sometimes being one of the few remote workers makes it easier to be forgotten…. Neurodivergent workers who spoke about their office struggles say even part-time remote work can be a game changer. They also wish leaders would seek input from them and trust them to get their work done.

Should College Application Essays Be Banned?

While college applicants are often required to write a personal essay for their applications, political scientist/author/academic Yascha Mounk argues that’s “a deeply unfair way to select students for top colleges, one that is much more biased against the poor than standardized tests.”

The college essay wrongly encourages students to cast themselves as victims, to exaggerate the adversity they’ve faced, and to turn genuinely upsetting experiences into the focal point of their self-understanding. The college essay, dear reader, should be banned and banished and burned to the ground.

There are many tangible, “objective” reasons to oppose making personal statements a key part of the admissions process. Perhaps the most obvious is that they have always been the easiest part of the system to game. While rich parents can hire SAT tutors they can’t sit the standardized test in the stead of their offspring; they can, however, easily write the admissions essay for their kid or hire a “college consultant” who “works with” the applicant to “improve” that essay. Even if rich parents don’t cheat in those ways, their class position gives rich kids a huge advantage in the exercise… [W]riting a good admissions essay is to a large extent an exercise in demonstrating one’s good taste — and the ability to do so has always depended on being fluent in the unspoken norms of an elite community…

Many on the left oppose standardized tests on the grounds that they have a class bias, and that hiring a tutor can make you perform better at them. But studies on the subject consistently suggest that the class bias of personal essays is far stronger than the class bias of standardized tests…. But the thing I truly hate about the college essay is not that it is part of a system that keeps deserving kids out of top colleges while rewarding privileged kids who (to add insult to injury) get to flatter themselves that they have been selected for showcasing such superior personality in their 750-word statements composed by their college consultant or ghostwritten by ChatGPT… [W]hat I truly hate about the college essay is the way in which it shapes the lives of high school students and encourages the whole elite stratum of society — including some of its most affluent, privileged and sheltered members — to conceive of themselves in terms of the hardships they have supposedly suffered…

[I]t is the bizarre spectacle of those kids from comparatively privileged backgrounds being effectively coerced by the admissions system to self-exoticize as products of great hardship which I find to be truly unseemly… And this is why I suspect that the seemingly innocuous institution of the college essay is more deeply damaging — to the high school experience, to the self-conception of millions of Americans, and even to the country’s ability to sustain a trusted elite — than it appears… [I]t drains the souls of teenagers and encourages a deeply pernicious brand of fakery and breeds widespread mistrust in social elites.

The college essay is absurd and unfair and — ironically — unforgivably cringe. It’s time to put an end to its strange hold over American society, and liberate us all from its tyranny.

The Last of Us season two ‘Through the Valley’ recap: Well, that happened

Spoilers follow for The Last of Us season two, episodes one and two

HBO’s The Last of Us showed viewers in season one that it would lean heavily on the source video games for major plot points and general direction of the season while expanding on the universe, and season two has followed that to the most extreme end possible. Episode two sees Tommy and Maria lead the town of Jackson Hole against a massive wave of Infected, the likes of which we haven’t seen in the show (or video games) yet. This was a complete invention for the show, one that gives the episode Game of Thrones vibes, or calls to mind a battle like the siege of Helm’s Deep in Lord of the Rings: The Two Towers. It’s epic in scale, with the overmatched defenders showing their skill and bravery against overwhelming odds; there is loss and pain but the good guys eventually triumph.

That mass-scale battle is paired with the most intimate and brutal violence we’ve seen in the entire series so far, as Joel’s actions finally catch up with him. His death at the hands of Abby and her crew of ex-Fireflies from Seattle is truly upsetting, even if you know it is coming — and that in the twisted world that Joel and Abby inhabit, it was a form of “justice.”

Of course, it was pretty obvious after the first five minutes of episode one that this is where Abby’s journey would take her, but it sure happened fast. You could say the same thing about when Joel dies in the video game, but ever since the HBO series was announced I’ve been wondering about just how Craig Mazin would choose to tackle the events of the second game and Joel’s death. Part of me wondered if we wouldn’t know for sure Joel was dead until near the end of the season, or if we might not find out Abby’s motivations until much later. But after two episodes, we know that Abby’s dad was the doctor Joel killed at the end of season one to save Ellie, a fact that makes her disturbing lust for vengeance more understandable to the television audience. In the game, on the other hand, players didn’t find that out until much later — a move that cast Abby in the role of “villain” that made Ellie’s own desire for revenge more relatable for the player

But what works in a game doesn’t necessarily work in a more passive adaptation. I do think there was a way for the writers to save the full reveal for Abby’s motivations for later, but I didn’t really bump on how things played out here. Similarly, I wasn’t really bothered by the introduction to Abby’s crew and her desire to find Joel that happened at the beginning of the season premiere. But I do know a number of people who played the game feel like this has robbed the show of some mystery and changed the momentum in a way that didn’t work for them, and I can appreciate that argument.

For anyone who hasn’t played the games, though, I’m sure that seeing the co-lead character killed off in the second episode of the season was a bit of a shock, no matter how much it was hinted at — particularly after Joel went out of his way to save Abby from certain death. In another world, you could imagine that blunting her need for revenge, or at least having her forgo the extended torture of a helpless Joel. But she’s clearly captivated by the opportunity in a way that even her friends are a bit horrified by. Ellie being there to find Dina unconscious and then forced to watch Abby deliver the final blow is the cherry on the disaster sundae that is this episode. It’s even harder to swallow when you consider their last interaction was Ellie’s extreme rebuff of Joel at the dance the night before.

It’s truly a wild choice for such a high-profile show, even though there was nowhere else for it to go. Pedro Pascal has been everywhere the last few years, and The Last of Us could have been his signature role. Joel’s death doesn’t fully diminish that, but obviously even if we see him in flashbacks in this season and the next, it won’t be the same as him leading an episode. To let such a marketable and popular star go must have been a tough pill for HBO to swallow, though chances are that the network knew from the beginning of negotiations that would have to happen. Regardless, it’s a move up there with the death of Sean Bean’s Ned Stark in terms of subverting audience expectations about who is going to lead the show going forward. That’ll fall to Bella Ramsey for the rest of the season.

I will say that Mazin and director Mark Mylod did a great job of balancing the many stories and cast members in this episode. Kaitlyn Dever gets her first extended amount of screen time and captures Abby’s barely-contained ferocity in a way that feels like a great tribute to the game source material, despite the fact that she is not nearly as physically ripped as Abby is in the game. Her scenes with Joel and Dina are absolutely chilling, even before she has Joel on the ropes; big credit to Pascal and Isabela Merced, again, for showing a major range of emotions as they help Abby escape from the Infected only to be betrayed.

Ramsey, meanwhile, shares a lot of time with Young Mazino’s Jesse as they go on patrol and frantically search for Joel; back in Jackson, Gabriella Luna and Rutina Wesley as Tommy and Maria keep Jackson from falling to the Infected. It’s a lot of threads to tie together, and the fact that this episode includes the biggest battle we’ve ever seen as well as Joel’s capture and death without feeling overstuffed is a testament to the writers, directors and cast.

Speaking of that Infected battle, I wasn’t fully sold on it when I saw teases in the trailers for this season, but it was a thrilling delight. I loved seeing the preparations Jackson put into place, like the oil barrels coming down from the walls and the flamethrower brigade surrounded by snipers up on the buildings. Of course, all the best-planned defenses fail once the Infected get through the wall and all hell breaks loose, and the show successfully had me questioning whether the town would make it even though the idea of it fully falling seemed like a deviation too far from the game. It definitely felt like a response to the criticisms of a relative lack of Infected action in season one, but it worked, and the juxtaposition of the disaster befalling Jackson at large as well as the smaller-scale loss of one of its most important citizens added another layer to the grief.

Infected Score: 11/10

The showrunners say season two will have more Infected than season one — let’s see if they’re sticking to their word.

Tommy taking down a Bloater with a flamethrower in front of a Mailboxes Etc. store? Barrels of oil lighting a field of Infected on fire? The extremely creepy reveal of the “live” Infected buried and laying in wait under a field of frozen ones that emerged and chased Abby right into the path of Joel? Jackson’s guard dogs coming to the rescue to keep the horde from overtaking the town? This was the most epic action we’ve seen out of the show yet, on a scale that we didn’t get in the games. It’ll be hard to top this battle.

Can You Run the Llama 2 LLM on DOS?

Slashdot reader yeokm1 is the Singapore-based embedded security researcher whose side projects include installing Linux on a 1993 PC and building a ChatGPT client for MS-DOS.

He’s now sharing his latest project — installing Llama 2 on DOS:

Conventional wisdom states that running LLMs locally will require computers with high performance specifications especially GPUs with lots of VRAM. But is this actually true?
Thanks to an open-source llama2.c project [original created by Andrej Karpathy], I ported it to work so vintage machines running DOS can actually inference with Llama 2 LLM models. Of course there are severe limitations but the results will surprise you.

“Everything is open sourced with the executable available here,” according to the blog post. (They even addressed an early “gotcha” with DOS filenames being limited to eight characters.)

“As expected, the more modern the system, the faster the inference speed…” it adds. “Still, I’m amazed what can still be accomplished with vintage systems.”
